Sperling's Partial Report Procedure
In 1960, George Sperling became the first to use a partial report paradigm to investigate the bipartite model of VSTM. In Sperling's initial experiments in 1960, observers were presented with a tachistoscopic visual stimulus for a brief period of time (50 ms) consisting of either a 3x3 or 3x4 array of alphanumeric characters such as:
- P Y F G
- V J S A
- D H B U
Recall was based on a cue which followed the offset of the stimulus and directed the subject to recall a specific line of letters from the initial display. Memory performance was compared under two conditions: whole report and partial report.

Famous quotes containing the words partial and/or report:
“America is hard to see.
Less partial witnesses than he
In book on book have testified
They could not see it from outside....”
—Robert Frost (1874–1963)
“There was never a man born so wise or good, but one or more companions came into the world with him, who delight in his faculty, and report it. I cannot see without awe, that no man thinks alone and no man acts alone, but the divine assessors who came up with him into life,—now under one disguise, now under another,—like a police in citizen’s clothes, walk with him, step for step, through all kingdoms of time.”
—Ralph Waldo Emerson (1803–1882)
